Elasticity, excellent retractility

Excellent remolding capability of foam ( restorable to the original shape, producible in random shape.

Polyurethane soft self-sintered skin ( ISF ) series, This is a kind of polyurethane porous foam with high plasticity. It is structurally divided into the high density surface layer ad low density core part, which are shaped simultaneously in one operation.

Polyurethane self-sintered skin product is widely used in sports apparatus, seating mat of gymnastic appliance, backrest, kneeling pad, handle, footboard, bike saddle, sport protective rings. It is also extensively used medical appliance, such as integrally shaped seating chair, edge seal of operating table, object hanging rack, wheel chair handle etc.

The self-sintered skin product is made in one operation by means of reaction injection molding ( RIM ), and therefore it has both tenacious and dense outer skin and cellulite core. The thickness of the skin formed varies from several tenths to 5 mm and the skin density from 600 to 1200 kg/m3 whereas the density of the inner core is hundreds of kilos per cubic meters.

The skin layer and the core layer are an integral body. The continuous, smooth and soft skin payer can protect the foam core from mechanical damage. Semi hard foam series of integral PU varies in different density and hardness depending on the recipe. The polyurethane is characterized by the fact that it can be sintered integrally with the material filled in the molding process. The basic features of this kind of foam are: extremely high anti-impact, light weighted, highly productive, variable hardness and abrasive-resistant everlasting elastic, easily colored on the surface, easily coloring the entire body, and intensifiable by inserts.

High density polyurethane hard foam plastic has some of the properties inherent with wood, it is possible to plane on, nail in and saw, hence the name of synthetic wood. It is also possible to mold into carves and patterns for various complicated structures. It is thus and effective way to solve the problem caused by the shortage of good quality wood and the lack of skilled workers.
